A shot of both bows...

 

 

All ready to glass!

 

Bottom & side glass is laid out....

 

...and now is epoxied.

 

 

Top & transom glass applied...

 

...and now epoxied!

 

 

A boring "porch paint" color...

 

...but cheap, tough, and quick.

 

 

I really like this shape...

 

...especially when fully painted.

 

 

Blocks are initially canted out at 10 degrees...

 

...but removable if change is needed.

 

 

Transom & rear mounting block...

 

Ready for sea trials...

 

 

10 degree cant proved excessive...

 

But 5 degrees was perfect!

...truly a quick and smooth boat now!
